Generally in a packet pair estimation, you are supposed to send multiple bursts of packet pairs and take an average of the bandwidths.
Say, you send 4 packets, calculate the time difference between the first two packets(1&2), time difference between the next two packets(3&4). Calculate bandwidth for each of these two and then take average.
Or
Calculate the time difference between (1&2), time difference between (3&2), time difference between (4&3)... and then take an average out of these values.
Which is the right method for average?
回答1:
If you use packet pair to estimate bandwidth, use the first method.
